wheel size INFINITI Q70 HYBRID 2014 User Guide

8-40Maintenance and do-it-yourself
The wheel nuts must be kept tigh-
tened to the specification at all
times. It is recommended that wheel
nuts be tightened to the specifica-
tion at each tire rotation interval.
WARNING
.After rotating the tires, check and
adjust the tire pressure.
. Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
. Do not include the T-type spare
tire or any other small size spare
tire in the tire rotation.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.

Tire wear and damage
1.Wear indicator
2.Wear indicator location mark
WARNING
. Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced. .
The original tires have built-in
tread wear indicators. When wear
indicators are visible, the tire(s)
should be replaced.
. Tires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician, because
some tire damage may not be
obvious. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
. Improper service of the spare tire
may result in serious personal
injury. If it is necessary to repair
the spare tire, contact an INFINITI
retailer.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.

Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. (See
“Specifications”(P.9-8) for recommended
types and sizes of tires and wheels.)
WARNING
. The use of tires other than those
recommended or the mixed use of tires
of different brands, construction (bias,
bias-belted or radial), or tread patterns
can adversely affect the ride, braking,
handling, ground clearance, body-to-tire
clearance, tire chain clearance, speed-
ometer calibration, headlight aim and
bumper height. Some of these effects
may lead to accidents and could result in
serious personal injury.
. If your vehicle was originally equipped
with 4 tires that were the same size and
you are only replacing 2 of the 4 tires,
install the new tires on the rear axle.
Placing new tires on the front axle may
cause loss of vehicle control in some
driving conditions and cause an accident
and personal injury. .
If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimension.
Wheels of a different off-set could cause
premature tire wear, degrade vehicle
handling characteristics and/or interfer-
ence with the brake discs/drums. Such
interference can lead to decreased brak-
ing efficiency and/or early brake pad/
shoe wear. See “Wheels and tires” (P.9-
8) of this manual for wheel off-set
dimensions.
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
. Do not install a damaged or deformed
wheel or tire even if it has been repaired.
Such wheels or tires could have struc-
tural damage and could fail without
warning. .
The use of retread tire is not recom-
mended.
. For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or“Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.Wheel balance
Unbalanced wheels may affect vehicle
handling and tire life. Even with regular
use, wheels can get out of balance. There-
fore, they should be balanced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the INFINITI Warranty Information Book-
let.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.

8-42Maintenance and do-it-yourself
Spare tire (TEMPORARY USE ONLY
(T-type) spare tire)
Observe the following precautions if the T-
type spare tire must be used, otherwise
your vehicle could be damaged or involved
in an accident.
WARNING
.The T-type spare tire should be used for
emergency use. It should be replaced
with the standard tire at the first
opportunity to avoid possible tire or
differential damage.
. Drive carefully while the TEMPORARY
USE ONLY spare tire is installed. Avoid
sharp turns and abrupt braking while
driving.
. Periodically check spare tire inflation
pressure. Always keep the pressure of
the TEMPORARY USE ONLY spare tire at
60 psi (420 kPa, 4.2 bar). Always keep
the pressure of the full size spare tire (if
so equipped) at the recommended pres-
sure for standard tires, as indicated on
the Tire and Loading Information label.
For Tire and Loading Information label
location, see “Tire and Loading Informa- tion label”
in the index of this manual.
. With the TEMPORARY USE ONLY spare
tire installed do not drive your vehicle at
speeds faster than 50 MPH (80 km/h).
. When driving on roads covered with
snow or ice, the TEMPORARY USE ONLY
spare tire should be used on the front
wheels and original tire used on the rear
wheels (drive wheels). Use tire chains
only on the two rear original tires.
. Tire tread of the TEMPORARY USE ONLY
spare tire will wear at a faster rate than
the standard tire. Replace the spare tire
as soon as the tread wear indicators
appear.
. Do not use the spare tire on other
vehicles.
. Do not use more than one spare tire at
the same time.
CAUTION
.Do not use tire chains on a TEMPORARY
USE ONLY spare tire. Tire chains will not
fit properly and may cause damage to
the vehicle. .
Because the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also do not drive
the vehicle through an automatic car
wash since it may get caught.

If you plan to travel in another country,
you should first find out if the fuel
available is suitable for your vehicle’ s
engine.
Using fuel with too low an octane rating
may cause engine damage. All gasoline
vehicles must be operated with unleaded
gasoline. Therefore, avoid taking your
vehicle to areas where appropriate fuel is
not available.
When transferring the registration of your
vehicle to another country, state, province
or district, it may be necessary to modify
the vehicle to meet local laws and regula-
tions.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications
may differ.
When any vehicle is to be taken into
another country, state, province or district
and registered, its modifications, trans-
portation, and registration are the respon-
sibility of the user. INFINITI is not
responsible for any inconvenience that
may result.
